Detailed Description

As shown in FIG. 1, the testing device mainly completes the resistance test of the temperature sensor 2, the angle cos sensor 3, the angle sin sensor 4, the angle EXC sensor 5 and the resistance test of the three-phase line 6. The basic principle is that the testing device inputs a resistance value range reflecting the normal state of the tested object in advance, and if the resistance value of the tested object exceeds the range during testing, the tested object can be determined to be unqualified or have a problem.

As shown in fig. 1-4, a portable motor resistance value testing device comprises a box body 1, a display 7, a main control board 8, a signal detection board 9 and a testing connection flat cable 10. The box body 1 is cuboid and comprises a front panel 101, a back panel 102, an upper side plate, a lower side plate 103, a left side plate and a right side plate 104. The size of the box body 1 is convenient to carry, and the smaller the size is, the better the size is on the premise of meeting the requirements of device installation and being convenient to control and read. The front panel 101 has a rectangular hole, the display 7 has a display screen 701, the display 7 is mounted on the front panel 101 in the box 1, and the display screen 701 is located in the rectangular hole.
